Vim li cas koj thiaj xav tau lub catalyst hauv lub tsheb
Cov tswv tsheb feem ntau nco qab lossis kawm txog qhov muaj nyob ntawm lub catalytic converter nyob rau hauv lub tso pa tawm ntawm lub tsheb tsuas yog thaum lawv hnov ib nqe lus zoo li "koj lub catalyst tuag" los ntawm tus neeg pabcuam. Nws yog ib qho yooj yim los daws nrog xws li ib tug malfunction, tab sis nyob rau hauv ntau txoj kev sib txawv.
Lub contraption, colloquially hu ua "catalyst", dais lub npe ntawm "Automotive Exhaust Catalytic Converter". Qhov no yog ib feem ntawm lub tso pa tawm ntawm lub tsheb, lub luag hauj lwm rau kev tshem tawm cov khoom tsim kev puas tsuaj rau tib neeg thiab ib puag ncig, xws li unburned hydrocarbons nyob rau hauv lub tog raj kheej, soot, carbon monoxide CO thiab nitrogen oxide NO, nyob rau hauv cov pa gases. Nyob rau hauv lub catalyst, tag nrho cov tshuaj no raug quab yuam tom qab hlawv, tig los ntawm cov khoom uas tsis tshua muaj aggression los ntawm ib tug tshuaj point of view: dej, CO2 thiab nitrogen. Qhov no tshwm sim vim muaj tshuaj lom neeg tshwm sim nyob rau hauv lub xub ntiag ntawm catalysts - radium, palladium thiab platinum.
Cov txheej txheem yuav tshwm sim thaum cov pa pa tawm mus los ntawm cov nplua-mesh ceramic lossis hlau honeycomb hauv "chim" ntawm catalytic converter, coated nrog ib qho alloy ntawm cov hlau tsis tshua muaj hauv ntiaj teb. Lub tsheb catalyst yog ib qho kim thiab luv luv. Txawm tias nyob rau hauv qhov zoo tshaj plaws, ob peb converters yuav "nyob" rau ntau tshaj 120 km. khiav. Lawv feem ntau ua tsis tau rau ntau yam. Ceramic catalysts tuaj yeem tawg ntawm tus nqi nrawm thaum lub tsheb nquag tsav dhau ntawm cov pob loj. Los ntawm co thiab tshuab, nyias phab ntsa ntawm honeycombs tritely tawg thiab chipped tawm.
Nyob rau hauv cov ntaub ntawv uas lub cav muaj teeb meem nyob rau hauv lub lubrication system, lub tog raj kheej-piston pab pawg neeg los yog ignition, unburned roj thiab roj los ntawm lawv lub tog raj kheej nkag mus rau hauv lub catalyst thiab kaw nws honeycombs nrog slag. Kwv yees li cov nyhuv tib yam muab kev hlub ntawm tus tswv ntawm lub tsheb nrog lossis tsis muaj laj thawj los nias lub roj pedal txhua txoj hauv kev hauv txhua qhov xwm txheej. Lub cev qhuav dej los yog clogged catalyst tsis tsuas yog tso tseg nws txoj haujlwm, tab sis kuj tseem cuam tshuam rau kev tawm ntawm cov pa tawm ntawm lub cav. Qhov no, nyob rau hauv lem, ua rau ib tug pom tau tias poob ntawm lub cav fais fab. Yuav ua li cas nrog ib tug ua tsis tau tejyam catalytic converter?
Thawj qhov uas los rau hauv siab yog hloov nws nrog tib yam, tab sis tsuas yog ib qho tshiab xwb. Qhov no yog qhov kev xaiv kim tshaj plaws. Tus nqi rau cov khoom lag luam tshiab catalytic converters ncav cuag tsib caug txhiab rubles. Yog li ntawd, feem ntau cov neeg tsav tsheb xaiv los hloov cov qub clogged catalyst nrog ib tug tsis yog-thawj los yog feem ntau universal qauv. Txhim kho lub catalyst uas ua tau raws li cov qauv Euro 4 hauv kev quab yuam hauv Russia tam sim no raug nqi txog 10 rubles. Yog tias qhov nyiaj no zoo li tsis tuaj yeem tiv taus, tom qab ntawd es tsis txhob siv cov khoom siv hluav taws xob, lub "chim" ntawm cov nplaim taws yog welded rau hauv qhov tso pa tawm thiab tib lub sijhawm lub cav tswj lub cav yog reprogrammed. Kev ua haujlwm kawg yog qhov tsim nyog kom cov pa oxygen sensor nyob rau hauv lub tso pa tawm, taw qhia tias cov catalyst tsis ua haujlwm, tsis cuam tshuam cov hluav taws xob "hlwb".
